Title: Evaluation of the reactivity ratios and sequence distribution in episulphide copolymers by 13C NMR
Abstract: The microstructure (in particular the distribution of the monomeric units) has been determined by means of 13C NMR for the three copolymers ethylene sulphide-propylene sulphide (ES-PS), ethylene sulphide-isobutylene sulphide (ES-IBS) and propylene sulphide-isobutylene sulphide (PS-IBS) prepared with anionic catalysts. Low and high conversion copolymers have been analysed. The results for the diad and triad fractions have been used for the evaluation of the reactivity ratios in the copolymerizations. The values are discussed and compared with those found using the Finemann and Ross method.
